Correct answer is: actual wingspan of airplane is 6 inches.
Solution:-
We are given that wingspan is 'a' feet and tail span is 'b' feet in a scale drawing.
And we are also given that tail span is 2 inches that is b=2 inches and 
Let us plugin the b value in above equation.

Multiplying with 2 on both sides.
a=3X2=6 inches.
Hence actual wingspan of airplane is 6 inches.
follow these steps:
1) y-4=7x^2
2) (y-4)/7 = x^2

so you must inverse x and y names:

19 x 3 = 57
57 - 9 = 48
Your answer is 19.
